5. The method of claim 4 wherein requesting the media-adaptation resource from the pool of media-adaptation resources capable of performing an IP to IP transcoding function includes selecting an MRFP and allowing the selected MRFP to determine an appropriate media-adaptation resource to provide.
6. The method of claim 4 wherein an MRFP of the one or more of MRFPs provides a media-adaptation resource from the pool of media-adaptation resources capable of performing an IP to IP transcoding function.
7. The method of claim 1 comprising:
configuring the plurality of MRFCs and the one or more MRFP for loose coupling.
8. The method of claim 7 wherein configuring the MRFCs and MRFPs includes configuring using at least one of:
a predetermined list;
an element management system (EMS) node;
a network operator; and
network analysis.
9. The method of claim 1 wherein an MRFC of the plurality of MRFCs comprises functionality in one of:
a media gateway controller (MGC);
a policy decision function (PDF);
a softswitch;
a media server;
a mobile switching center (MSC) server;
an application server (AS);
a media resource function (MRF); and
an interconnect border control function (IBCF).
10. The method of claim 1 wherein an MRFP of the one or more MRFPs comprises functionality in one of:
a media gateway (MG);
a gateway function;
a media server;
a transition gateway (TrGW);
an interconnect border gateway function (I-BGF);
a core border gateway function (C-BGF);
a media resource function (MRF); and
an access border gateway function (A-BGF).
11. The method of claim 1 comprising:
receiving, by at least one MRFC, resource usage information related to an MRFP.
12. The method of claim 11 wherein receiving resource usage information includes periodically auditing the MRFP for current usage and capacity statistics.
13. The method of claim 12 wherein current usage and capacity statistics includes information for determining number of available media-adaptation resources for use and total number of media-adaptation resources of the MRFP.
14. The method of claim 1 wherein MRFP-related interactions include requesting media-adaptation resources.
15. A system for loose coupling of media resource function controllers (MRFCs) and media resource function processors (MRFPs), the system comprising:
one or more MRFPs having media processing resources simultaneously usable by a plurality of MRFCs; and
a plurality of MRFCs for simultaneously using the media processing resources of the one or more MRFPs, wherein the plurality of MRFCs is organized into two or more controller groups, wherein each controller group is operable to handle MRFP-related interactions for other controller groups if a failure occurs.
16. The system of claim 15 wherein the media processing resources are media adaptation resources for Internet protocol (IP) to IP transcoding.
17. The system of claim 15 wherein the plurality of MRFCs and the one or more MRFP are configured for loose coupling.
18. The system of claim 15 wherein the plurality of MRFCs are configured with information about one or more MRFPs capable of providing media-adaptation resources using at least one of:
a predetermined list;
an element management system (EMS) node;
a network operator; and
network analysis.
19. The system of claim 15 wherein an MRFC of the plurality of MRFCs comprises functionality in one of:
a media gateway controller (MGC);
a policy decision function (PDF);
a softswitch;
a media server;
a mobile switching center (MSC) server;
an application server (AS);
a media resource function (MRF); and
an interconnect border control function (IBCF).
20. The system of claim 15 wherein an MRFP of the one or more MRFPs comprises functionality in one of:
a media gateway (MG);
a gateway function;
a media server;
a transition gateway (TrGW);
an interconnect border gateway function (I-BGF);
a core border gateway function (C-BGF);
a media resource function (MRF); and
an access border gateway function (A-BGF).
21. The system of claim 15 wherein at least one MRFC receives resource usage information related to an MRFP.
22. The system of claim 21 wherein receiving resource usage information includes periodically auditing the MRFP for current usage and capacity statistics.
23. The system of claim 22 wherein current usage and capacity statistics includes information for determining number of available media-adaptation resources for use and total number of media-adaptation resources of the MRFP.
24. The system of claim 15 wherein media-adaptation resources of the one or more MRFPs are logically grouped into a pool of media-adaptation resources.
25. The system of claim 24 wherein an MRFC of the plurality of MRFCs requests a media-adaptation resource from the pool of media-adaptation resources capable of performing an IP to IP transcoding function.
26. The system of claim 25 wherein requesting the media-adaptation resource from the pool of media-adaptation resources capable of performing an IP to IP transcoding function includes selecting an MRFP and allowing the selected MRFP to determine an appropriate media-adaptation resource to provide.
27. The system of claim 26 wherein an MRFP of the one or more MRFPs provides a media-adaptation resource from the pool of media-adaptation resources capable of performing an IP to IP transcoding function.
28. The system of claim 15 wherein MRFP-related interactions include requesting media-adaptation resources.
29. A non-transitory computer readable medium having stored thereon executable instructions that when executed by the processor of a computer control the computer to perform steps comprising:
providing one or more MRFPs having media processing resources simultaneously usable by a plurality of MRFCs; and
at one of the MRFPs, allowing a plurality of MRFCs to simultaneously use the media processing resources of the MRFP, wherein the plurality of MRFCs is organized into two or more controller groups, wherein each controller group is operable to handle MRFP-related interactions for other controller groups if a failure occurs.
